Closure device having closure parts which are able to be placed against one another

A closure device comprising

• a first closure part which has a body, and a second closure part, said first closure part and said second closure part for closing the closure device being able to be placed against one another along a closing direction and in a closing position being connected to one another;
• and
• at least one locking element which is adjustable in relation to the body of the first closure part;
• and
• at least one engagement portion which is shaped on the second closure part, wherein the at least one locking element and the at least one engagement portion in a closing position are mutually engaged in such a manner that the first closure part and the second closure part are locked to one another,
• wherein the first closure part has a first magnetic installation, and the second closure part has a second magnetic installation, wherein the first magnetic installation and the second magnetic installation when placing the first closure part and the second closure part against one another interact in a magnetically attractive manner, and the at least one locking element is magnetically configured in such a manner that the at least one locking element in the closing position by way of the first magnetic installation and/or the second magnetic installation is loaded in a direction of engaging with the at least one engagement portion, wherein the first closure part has an adjustment part and an operative element which is operatively connected to the adjustment part and is rotatable about a rotation axis, wherein the adjustment part by rotating the operative element is activatable in an activation direction so as to bring the at least one locking element to disengage from the at least one engagement portion in order for the first closure part and the second closure part to be released from one another, and
• wherein the operative element has a guiding installation on which the adjustment part is guided in such a manner that the adjustment part when rotating the operative element is activated in the activation direction.

A closure device comprising

• a first closure part which has a body, and a second closure part, said first closure part and said second closure part for closing the closure device being able to be placed against one another along a closing direction and in a closing position being connected to one another;
• and
• at least one locking element which is adjustable in relation to the body of the first closure part;
• and
• at least one engagement portion which is shaped on the second closure part, wherein the at least one locking element and the at least one engagement portion in a closing position are mutually engaged in such a manner that the first closure part and the second closure part are locked to one another,
• wherein the first closure part has a first magnetic installation, and the second closure part has a second magnetic installation, wherein the first magnetic installation and the second magnetic installation when placing the first closure part and the second closure part against one another interact in a magnetically attractive manner, and the at least one locking element is magnetically configured in such a manner that the at least one locking element in the closing position by way of the first magnetic installation and/or the second magnetic installation is loaded in a direction of engaging with the at least one engagement portion, wherein the first closure part has an adjustment part and an operative element which is operatively connected to the adjustment part and is rotatable about a rotation axis, wherein the adjustment part by rotating the operative element is activatable in an activation direction so as to bring the at least one locking element to disengage from the at least one engagement portion in order for the first closure part and the second closure part to be released from one another, and
• wherein the at least one locking element is received so as to be adjustable in a receptacle opening of the first closure part.

A closure assembly having a plurality of closure devices which comprise in each case:

• a first closure part which has a body, and a second closure part, said first closure part and said second closure part for closing the closure device being able to be placed against one another along a closing direction and in a closing position being connected to one another;
• and
• at least one locking element which is adjustable in relation to the body of the first closure part;
• and
• at least one engagement portion which is shaped on the second closure part, wherein the at least one locking element and the at least one engagement portion in a closing position are mutually engaged in such a manner that the first closure part and the second closure part are locked to one another,
• wherein the first closure part of each closure device has a first magnetic installation, and the second closure part of each closure device has a second magnetic installation, wherein the first magnetic installation and the second magnetic installation when placing the first closure part and the second closure part against one another interact in a magnetically attractive manner, and the at least one locking element is magnetically configured in such a manner that the at least one locking element in the closing position by way of the first magnetic installation and/or the second magnetic installation is loaded in a direction of engaging with the at least one engagement portion, wherein the first closure part of each closure device has an adjustment part and an operative element which is operatively connected to the adjustment part, wherein the adjustment part by adjusting the operative element is activatable in an activation direction so as to bring the at least one locking element to disengage from the at least one engagement portion in order for the first closure part and the second closure part to be released from one another, wherein the closure assembly has an activation element which by way of a transmission connection is connected to the operative elements of the first closure parts of the plurality of closure devices in such a manner that the operative elements are conjointly adjustable by activating the activation element.
